The GX6256 Low Frequency multiplexer 6U PXI card has sixteen 2x16 switching groups connected to 256 channels tied to selectors. Each channel has a primary path and a secondary path. The primary path is designed for optimum performance while the secondary path is intended to be used for DC signal.
The board consists of a multiplexer, matrix and selectors. The GX6256 connects to 16 analog signals through the backplane and to 16 digital signals through a connector in the bottom. Input selectors select the analog or digital input for each multiplex group. Each group routs this signal to one of sixteen channels that are connected to the front connectors.
